For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element without departing from the teachings of the disclosure. Although some of the diagrams include arrows on communication paths to show a primary direction of communication, it is to be understood that communication may occur in the opposite direction to the depicted arrows.

As discussed above, conventional tools for diagnosing biopsies are generally slow, inefficient and inaccurate. At least a fifth of all patients are called back to repeat a biopsy deemed inadequate. Accordingly, some embodiments of the present inventive concept provide a system for rapid on-site evaluation (ROSE) of biological tissues that improves speed, efficiency and accuracy of biopsies. Some embodiments of the present inventive concept greatly reduce the number of repeat biopsies needed, save costs associated with personnel and rooms and may greatly increase revenue associated with biopsy procedures as will be discussed further herein with respect to FIGS. 1 through 34.

As used herein, a “biopsy” refers to an examination of tissue or cells removed from a living body to discover the presence, cause, or extent of a disease. The tissue or cells may be human or animal tissue without departing from the scope of the present inventive concept. For the purposes discussed herein, biopsies may be used for patient case as well as research without departing from the scope of the present inventive concept. Furthermore, “biopsies” as used herein is intended to include any biological material for staining in accordance with embodiments discussed herein. Thus, even biological material not obtained in an official “biopsy” is intended to be included in the term “biopsy.”

Furthermore, various embodiments of the present inventive concept are discussed herein with respect to an “insert.” The insert is positioned in a housing used to stain the material placed in the insert. In some embodiments, the “insert” is termed a “biopsy insert.” However, it will be understood that embodiments of the present inventive concept are not limited to biopsy insert. Any material may be placed in the insert that is capable of being “stained” in accordance with embodiments of the present inventive concept without departing from the scope of the present inventive concept. In some embodiments, the material is a biological material including at least some cells.

Referring first to FIG. 1, a high-level block diagram of a system in accordance with embodiments of the present inventive concept will be discussed. As illustrated in FIG. 1, the system 180 includes a hardware component 190, a disposable component 193 and a software component 195. As shown, the hardware component comprises an imaging system that delivers high quality digital images of whole biopsies without destruction at subcellular resolution. The imaging system may include a digital microscope as well as other components. The imaging system may use methods and systems discussed in United States Patent Publication No. 2016/0062098 entitled Microscopy of a Tissue Sampling Using Structured Illumination to Brown, the content of which is hereby incorporated herein by reference as if set forth in its entirety. Brown discusses use of structured illumination microscopy to generate digital histology images of fresh tissues stained by fluorescent dyes. These methods may be used in embodiments of the present inventive concept.

The software component 195 may include processors and algorithms to provide a centralized telepathy evaluation user experience. Thus, the software component 195 is capable of evaluating the biopsies and reporting results in a format that is consumable by a user including users remote from the system 180.

The disposable component 193 enables hands-free tissue processing, which will be discussed further below with respect to FIGS. 2 through 14. Accordingly, systems 180 in accordance with embodiments discussed herein provide a user friendly, high resolution imaging system for fresh whole biopsy tissue. Methods provide a one step, accurate ROSE workflow having a 93 percent accuracy, much improved over the conventional 80 percent.

Referring now to FIGS. 2A through 2C, a disposable in accordance with some embodiments of the present inventive concept will be discussed. The disposable 293 includes an insert 296 (a) and a staining and imaging chamber 294 (b). As illustrated in FIG. 2A, the biopsy (a) 297 is placed in the well of the insert 296 (b). In FIG. 2B, the insert 296 is positioned into the staining/imaging chamber 294 (c) and the disposable is ready for placement in system dock in FIG. 2C. The system dock will be discussed further below.

It will be understood that although embodiments of the present inventive concept refer to an insert that receives the biopsy and that the term “insert” implies that it is actually inserted into something, for example, the staining chamber/carrier, embodiments of the present inventive concept are not limited thereto. For example, embodiments may be envisioned where the mechanism that receives the biopsy may not be inserted into any holder. Thus, the insert may be referred to as “insertable” implying that may or may not be inserted.

Referring now to FIGS. 3A through 3E, the disposable 293 is placed in the system dock 285 as illustrated in FIG. 3A. Feeder wheels (d) are configured to forward the disposable 293 into place. In some embodiments, a spring seal is pressed down onto the slide, creating a seal. Stain-containing syringes located within in the disposable 293 are actuated by linear motors housed on the stage (e) as shown in FIG. 3B, pushing stain onto the biopsy tissue. The force pushing the spring seal is released, allowing stain to be removed from the imaging window. The stage is stepped in a serpentine pattern over the objective lens of the microscope as the tissue is imaged as illustrated in FIG. 3C.

After imaging, the feeder wheels are reversed as illustrated in FIG. 3D, and the disposable 293 is removed from the system dock 285. The insert is removed from the disposable 293 as illustrated in FIG. 3E. The biopsy is removed from the insert. The insert is discarded, and the biopsy is set aside for downstream processing.

The process discussed with respect to FIGS. 3A through 3E may be repeated with the same staining/imaging chamber until all biopsies for a single organ site have been imaged. In some embodiments, the staining/imaging chamber may only be used a maximum of five timed before it is discarded.

FIG. 4 is an exploded view of the staining/imaging chamber including an insert in accordance with some embodiments of the present inventive concept. As illustrated the disposable module includes a top shell (1); syringe plungers (2); syringe barrels (3); leur-lock barbed connectors (4); stain transport tubes (5); syringe manifold (6); manifold seal (7); sled (8); sled gasket (9); bottom shell (10); insert body (11); spring seal body (12); spring seal gasket (13); linear wave springs (14); PVA sponge (15); and imaging window (16). Embodiments of the present inventive concept illustrated in FIG. 4 are provided as an example only, thus, embodiments of the present inventive concept are not limited thereto.

Referring now to FIGS. 5A through 14, the process of obtaining a biopsy and imaging the biopsy using a disposable module in accordance with embodiments of the present inventive concept will be discussed. FIGS. 5A and 5B are diagrams illustrating a first step in a process discussed herein. FIG. 5A is a diagram of the staining/imaging chamber and the insert in accordance with some embodiments of the present inventive concept. FIG. 5B is a cross section along the A of FIG. 4B of the insert in accordance with some embodiments of the present inventive concept. Referring first to FIG. 5A, a biopsy 297 (defined above) is positioned in a well of the insert 296 (FIG. 5B). In some embodiments, the biopsy 297 may rest in a thick acrylic window (c) 298. The materials provided herein are provided for example only and, therefore, embodiments of the present inventive are not limited thereto.

It will be understood that FIGS. 5A and 5B are provided for example only and that embodiments of the present inventive concept are not limited to this configuration. For example, in some embodiments, the biopsy could be placed on a microscope slide. The microscope slide would then be placed in the insert.

FIGS. 6A through 6D are diagrams illustrating a second step in a process discussed herein. FIGS. 6A and 6B are diagrams illustrating the staining/imaging chamber and an insert of a disposable module 293 in accordance with some embodiments of the present inventive concept. FIG. 6C is a cross section along the line B of FIG. 6A of the insert in accordance with some embodiments of the present inventive concept. FIG. 6D is a cross section along the line C of FIG. 6B of the insert in accordance with some embodiments of the present inventive concept. As illustrated in FIGS. 6A and 6B, the insert 296 is pushed (positioned) into the staining/imaging chamber (d) 294. Inclined planes (e) on the left and right sides of the insert displace the sled (f) (FIG. 6C) in the +y direction. A hollow barb (g) (FIG. 6C) located on the top of the sled punctures a thin barrier on the syringe manifold (h) (FIG. 6C). The +y direction displacement of the sled (f) causes an o-ring that is located at the base of the hollow barb on top of the sled (f) to made a seal with the bottom of the syringe manifold (h). Once the insert 296 is properly positioned in the chamber 294, the disposable module is ready to be placed in the system dock as will be discussed below.

It will be understood that FIGS. 6A through 6D are provided for example only and that embodiments of the present inventive concept are not limited to this configuration. For example, the disposable could have a “clam-shell” type lid that the biopsy holder is placed into. This embodiment would have an SD card like mechanism (push-push mechanism) and a threaded piece could secure the two together. A puncture port could be located at the rear of the staining chamber. These embodiments would lend well to using suction to for stain delivery.

FIGS. 7A through 7C are diagrams illustrating a third step in a process discussed herein. FIGS. 7A through 7C are diagrams of the system dock and the disposable module in various stages during positioning of the disposable module in the system dock in accordance with some embodiments of the present inventive concept. As illustrated in FIG. 7A, the disposable module 293 is placed in the system dock (i) 285 which is formed by the space between the microscope stage (j) and the disposable insertion guide (k).

Once the disposable module 293 is partially inserted, illumination from an LED (not pictured) is cut off from a photoresistor (not pictured). Both the LED and the photoresistor are housed in the disposable insertion guide (k) in these embodiments. The corresponding drop in resistance in the photoresistor is detected by a microcontroller (not pictured) which directs a stepper motor (1) (FIG. 7B) to spin clockwise about the y-axis. The shaft of the stepper motor is attached to a central gear (m) which meshes with two outer gears (n) as show in FIG. 7B. This creates a rotational motion (in opposite directions) of the feeder wheels (o). The disposable module 293 is pushed far enough into the system dock to make contact with the feeder wheels to be pulled into the system as illustrated in FIG. 7B. The disposable module 293 continues to be forwarded onto the stage by the feeder wheels (o) until the back of the disposable makes contact with a limit switch (not pictured) which is located at the back of the stage insert (p) shown in FIG. 7C.

It will be understood that FIGS. 7A through 7C are provided for example only and that embodiments of the present inventive concept are not limited to this configuration. For example, the disposable could be placed on the stage from the top, not the side. In these embodiments, the disposable could be inserted like an SD card (push-push mechanism). Multiple disposables could be placed at once in some sort of feeder mechanism.

Furthermore, other mechanisms for detection of the disposable may be used without departing from the scope of the present inventive concept. For example, a button contact, an IR beam detector (like a garage door), a force sensor, a magnetic field sensor and the like. Similarly, alternative mechanism for moving the disposable into the chamber may be used. For example, a conveyor belt, magnets, arms that grip each side, suction, linear servos that pull after attached to disposable and the like. Alternatives to the limit switch may include a magnetic sensor, a photoresistor, an IR beam detector, a force sensor, a user could position disposable and the like.

FIGS. 8A and 8B are diagrams illustrating a fourth step in a process discussed herein. FIGS. 8A and 8B are diagrams illustrating a spring seal mechanism in accordance with some embodiments of the present inventive concept. After the disposable has been properly placed on the microscope stage discusses above, a spring mechanism is configured to press down on the spring seal (q) that resides within the insert as illustrated in FIG. 8A. This downward force (r) will counteract the upward force provided by the linear wave springs (s) which would otherwise lift the spring seal off the imaging window (t). On the bottom of the spring seal mechanism is the spring seal gasket (u). When the downward force is applied to the spring seal, this gasket creates a seal with the imaging window as show in FIGS. 8A and 8B.

FIGS. 9A through 9D are diagrams illustrating a fifth step in the process discussed herein. FIG. 9A is a plan view of the system dock having the disposable module positioned therein in accordance with some embodiments of the present inventive concept. FIG. 9B is a side view of the system dock of FIG. 9A in accordance with some embodiments of the present inventive concept. FIGS. 9C and 9D are magnified views of portion D of FIG. 9A in accordance with some embodiments of the present inventive concept. As illustrated in FIG. 9C, stain-containing syringes (v) located within in the disposable are actuated by linear motors (w) (FIG. 9D) housed on the stage. This causes stain to move from the syringe, a tube (not pictured), through the syringe manifold (not pictured), through the hollow barb in the sled (not pictured), and onto the biopsy (not pictured).

Staining in accordance with some embodiments of the present inventive concept will now be discussed with respect to FIGS. 10A through 10C. FIGS. 10A through 10C are cross sections of the disposable module having the insert positioned there in accordance with some embodiments of the present inventive concept. As illustrating FIG. 10B, stain-containing syringes are located within in the disposable module. In some embodiments, these syringes are activated by linear motors housed on the stage. As illustrated in FIG. 10C, this causes stain to move from the syringe, into a tube, through the syringe manifold, through the hollow barb in the sled, and onto the biopsy insert, staining the biopsy in accordance with some embodiments of the present inventive concept.

It will be understood that FIGS. 9A through 10D illustrate an example only and embodiments of the present inventive concept are not limited thereto. For example, a screw-driven mechanism, linear actuators, linear servos, stepper motors with rack and pinion, pneumatic, magnetic, pumps (positive and negative pressure), gravity, an external mechanism that attached to disposable outside of system, then disposable is put in position, user could push stains manually, biopsy could be stained before placement in disposable and the like may be used. Furthermore, the movement may be accomplished by allowing the stage to move, the disposable to move, the object to move and the like. Alternatively, a wide field of view (FOV) may be used so the nothing has to move.

FIGS. 11A through 11F are diagrams illustrating a sixth step in the process discussed herein. FIGS. 11A through 11E are diagrams illustrating the insert and spring seal mechanism in accordance with some embodiments of the present inventive concept. FIG. 11F is a cross section along the line E of FIG. 11E in accordance with some embodiments of the present inventive concept. FIGS. 11A through 11F illustrate a method where force on the spring seal mechanism is released after a certain amount of time, allowing the stain to flow under the gasket and make contact with the PVA sponge.

In particular, as illustrated in FIG. 11A, stain from the syringes moves onto the biopsy via the previously described pathway and is held in place around the biopsy by the spring seal. Force on the spring seal is maintained for a certain amount of time during which the biopsy is stained as shown in FIG. 11B. FIG. 11C illustrates releasing the force on the spring seal, allowing the linear wave springs on the underside of the spring seal to push the mechanism up, removing the gasket from the slide and releasing the stain and allowing it to come into contact with the PVA sponge which wicks it off of the slide as will be discussed below. FIG. 11F illustrates a wash pushed onto the biopsy via the same pathway as the stain.

After the downward force on the spring seal mechanism has been released, linear wave springs lift the mechanism off the imaging window. This allows stain to flow under the previously compressed gasket and make contact with the PVA sponge as illustrated in FIG. 11F. The sponge wicks the stain away from the biopsy but leaves the biopsy in place to be imaged.

The final steps, seven and eight, of the process discussed herein will be discussed with respect to FIGS. 12 through 14. Referring now to FIG. 12, one the process is complete as discussed above, the stage is stepped in the x-z plane in a serpentine pattern over the objective (x) as the tissue is imaged. After imaging, the feeder wheels are reversed and the disposable is removed from the system dock as illustrated in FIG. 13. The, the insert is removed from the disposable as illustrated in FIG. 14. The biopsy is removed from the insert. The insert is discarded and the biopsy is set aside for downstream processing. The process discussed with respect to FIGS. 5A through 14 may be repeated with the same staining/imaging chamber until all biopsies for a single organ site have been imaged. In some embodiments, staining/imaging chamber may be used a maximum of five times. Thus, FIGS. 12 through 14 illustrate the disposable module being removed from the system and the biopsy is removed from the disposable module.

As discussed briefly above, some embodiments of the present inventive concept provide a system for rapid on-site evaluation (ROSE) of biological tissues that improves speed, efficiency and accuracy of biopsies.

Further embodiments of disposables 3593 in accordance with some embodiments of the present inventive concept will be discussed below with respect to FIGS. 35A through 47B. Referring to FIGS. 35A through 35C, various stages of a biopsy being placed in the biopsy insert will be discussed. FIG. 35A is an isometric view of a biopsy 3597 being placed in the biopsy well 3577 of the biopsy insert 3596. FIG. 35B is an isometric view of the biopsy insert 3596 being slid into the insert slot 3578 of the staining cartridge/chamber 3594. FIG. 35C is an isometric view of the staining cartridge/chamber 3594 having the biopsy insert 3596 positioned therein with the biopsy 3597 in place. In some embodiments, the biopsy 3597 may be removed from, for example, a biopsy gun, using tweezers and may be placed in the biopsy well 3577 of the of the biopsy insert 3596 where it rests on the imaging window 3501 as shown in FIG. 35A. The biopsy insert 3596 is then pushed into the staining cartridge/chamber 3594 through the insert slot 3578 as shown in FIGS. 35B and 35C.

FIGS. 36A through 36D will now be discussed. FIG. 36A is an isometric view illustrating the relative positions of the Sled 3602 and biopsy insert 3596 prior to placing the biopsy insert 3596 into the staining cartridge (not shown). FIG. 36B is a diagram illustrating the relative positions of the sled 3602 and the biopsy insert 3596 after the biopsy insert 3596 has been placed in the staining cartridge (not shown). The sled 3602 is pushed up by the biopsy insert 3596 via interaction between the adjacent inclined planes (Insert) 3604 and the adjacent inclined planes (sled) 3606 as shown in FIG. 36C. FIG. 36C is a side view of FIG. 36A illustrating the relative positions of the sled 3602 and biopsy insert 3596 prior to the biopsy insert 3596 being placed in the staining cartridge (not shown). Similarly, FIG. 36D is a side view of FIG. 36B illustrating the relative positions of a sled 3602 and biopsy insert 3596 after the biopsy insert 3596 has been placed in the staining cartridge (not shown). The sled 3602 is pushed up by the biopsy insert 3596 via interaction between the adjacent inclined planes (Insert) 3604 and the adjacent inclined planes (sled) 3606.

The carriage shaft 6851 runs through a linear ball bearing 6461 and is held in place on both ends by carriage shaft collars 6853. The staining cartridge 3594 is slid into the carriage 3941 with the biopsy insert 3596 facing outwards, away from the stage. Haptic feedback ridges (bottom shell) 4861 on the bottom shell 4863 interact with corresponding haptic feedback ridges (Carriage) 6171 on the carriage 3941 to deliver haptic feedback to the user once the staining cartridge 3594 has been pushed far enough into the carriage 3941. After the staining cartridge 3594 has been placed, the carriage 3941 is retracted back onto the stage via the same stepper motor 3851, lead screw 3853, lead nut 3855 mechanism as illustrated in FIGS. 39A though 39C.

It will be understood that embodiments illustrated above are provided for example only and, thus, do not limit the present inventive concept. For example, although embodiments are discussed herein with respect to the stepper motor, lead screw and lead nut mechanism used to move the carriage, other methods may be used. These mechanisms may include a rack-and-pinion, linear servos, or conveyor belt without departing from the scope of the present inventive concept. In some embodiments, a limit switch may not be used to halt the movement of the stepper motor. In these embodiments, alternate ways to halt the movement of the stepper motor may include a magnetic sensor or a light emitting diode (LED)-Photoresistor pair.

FIGS. 40A is a diagram. illustrating carriage in the fully retracted position prior to the clamp mechanism assembly deploying the cartridge clamp in accordance with some embodiments of the present inventive concept. FIG. 40B is a diagram of the carriage in the fully retracted position and the cartridge clamp deployed by the cartridge clamp linear servo in accordance with some embodiments of the present inventive concept.

In particular, the clamp mechanism assembly 4081 including the cartridge clamp 4083 and the clamp linear servo 4085 will be discussed. The clamp mechanism assembly 4081 serves at least two purposes. First, the cartridge clamp 4083 holds the staining cartridge 3594 in place on the stage. Second, the cartridge clamp 4083 presses down on the spring seal stamp 5391 (FIG. 53) via the spring seal stamp pegs 5393 (FIG. 53). Once the carriage 3941 has been fully retracted, the cartridge clamp linear servo 4085 deploys the cartride clamp 4083 which presses down on top of the staining cartridge 3594 as shown in FIGS. 40A and 40B. In some embodiments, the cartridge clamp 4083 may be actuated by a stepper motor or solenoid.

FIG. 41A is a diagram of the staining cartridge having the biopsy insert in place in accordance with some embodiments of the present inventive concept. FIG. 41B is a diagram illustrating the orientation between the staining cartridge and the cartridge clamp prior to the deployment of the cartridge clamp in accordance with some embodiments of the present inventive concept. FIG. 41C is a diagram illustrating the orientation between the staining cartridge and the cartridge claim after the deployment of the cartridge clamp in accordance with some embodiments of the present inventive concept. FIG. 41D is a side view illustrating orientation of top shell and the spring seal stamp in accordance with some embodiments of the present inventive concept. FIG. 41E is a side view illustrating orientation of the top shell, the spring seal stamp, and the cartridge claims prior to the deployment of the cartridge clamp in accordance with some embodiments of the present inventive concept. FIG. 41F is a side view illustrating orientation of the top shell, the spring seal stamp, and the cartridge clamp after the deployment of the cartridge clamp in accordance with some embodiments of the present inventive concept. It will be understood that some components of the present inventive concept have not been shown in FIGS. 41A through 41F for clarity. As shown in FIGS. 41A through 41F, the cartridge clamp pegs 8291 of the on the bottom of the cartridge clamp 4083 transfer the downward force of the cartridge clamp linear servo 4085 to the spring seal stamp 5391, pushing it down.

The spring seal stamp holes (top shell) 4943 in the top shell 4110 allow for the cartridge clamp pegs 8291on the bottom of the cartridge clamp 4083 to apply force to the spring seal stamp 5391. The spring seal stamp 5391 has corresponding extrusions that, when not being pushed, rest in the spring seal stamp holes (top shell) 4943. The spring seal stamp 5391 transfers the force from the cartridge clamp 4083 to the spring seal 5210 through the spring seal stamp holes (sled) 5020 in the top surface of the sled 3602 as illustrated in FIGS. 41A through 41F.

FIG. 42A is a diagram illustrating relative positions of the spring seal stamp and the sled in accordance with some embodiments of the present inventive concept. FIG. 42B is a diagram illustrating relative positions of the spring seal stamp and the spring seal in accordance with some embodiments of the present inventive concept. In particular, as illustrated in Fig, On the bottom of the spring seal stamp 5391 are two restoring springs 5395. These restoring springs 5395 apply force between the spring seal stamp 5391 and the sled 3602. This serves two purposes: to push the sled 3602 back down when the biopsy insert 3596 is eventually removed; and to restore the spring seal stamp 5391 to its original position when the cartridge clamp 4083 is retracted as shown in FIGS. 42A and 42B.

FIG. 43A is a diagram illustrating orientation between the biopsy insert, the sled and the spring seal stamp in accordance with some embodiments of the present inventive concept. FIG. 43B is a diagram illustrating orientation between the biopsy insert and the spring seal stamp in accordance with some embodiments of the present inventive concept. FIG. 43C is a diagram illustrating orientation between the spring seal and the imaging window of the biopsy insert in accordance with some embodiments of the present inventive concept. FIG. 44F is a side view of the orientation between the spring seal, spring seal gasket and imaging window prior to the spring seal stamp pushing down on the spring seal in accordance with some embodiments of the present inventive concept. FIG. 43E is a side view illustrating orientation between the spring seal, spring seal gasket, and imaging window after the spring seal stamp pushes down on the spring seal in accordance with some embodiments of the present inventive concept. This results in the spring seal gasket making contact with the imaging window and the formation of a seal.

As illustrated, the spring seal 5210 is the component of the biopsy insert 3596 that is responsible for creating a seal around the biopsy. On the bottom surface of the spring seal 5210 are spring tabs 5220 that, when not being pushed down, lift the spring seal 5210 off the imaging window 3501. When the spring seal 5210 is being pushed down, however, this lifting force provided by the spring tabs 5220 is overcome by the downward force provided by the spring seal stamp 5391, which is pushed by the cartridge clamp 4083, which is pushed by the cartridge clamp linear servo 4085 as illustrated in FIGS. 43A through 43E. On the bottom of the spring seal 5210 is the spring seal gasket 5510 (FIG. 55). The spring seal gasket 5510 creates a seal with the imaging window 3501 when the spring seal 5210 is pressed down.

In some embodiments, the spring tabs on the bottom of the spring seal may not be inherent to the body of the spring seal. In these embodiments, alternate methods of lifting the spring seal off of the imaging window may include, for example, a linear wave spring or similar spring type.

FIG. 44A is a diagram illustrating a stage adapter assembly 8410 with staining cartridge in place and carriage fully retracted in accordance with some embodiments of the present inventive concept. FIG. 44B is a diagram illustrating orientation between the staining cartridge and the carriage linear servos when the staining cartridge is placed on the carriage in accordance with some embodiments of the present inventive concept. FIG. 44C is a diagram illustrating orientation between the carriage linear servos and the inner components of the staining cartridge with the biopsy insert in place in accordance with some embodiments of the present inventive concept.

As illustrated, with the staining cartridge 3594 held in place and the spring seal 5210 deployed by the force of the cartridge clamp 4083, the biopsy is ready to be stained. The carriage linear servos 6210 housed in the linear servo bay 6173 in the back of the carriage 3941 actuate to push plungers within stain syringes 5610 that are loaded with stain or wash and housed within the staining cartridge 3594. The stain syringes 5610 are held in place by the syringe slots (Bottom Shell) 4865 and the syringe slots (Top Shell) 4945. Stain is pushed from the stain Syringes 5610, through the stain transport tubes 5620 into the stain manifold 3723, though the piercing barb 3720 on the sled 3602, and into the biopsy well 3577 where it stains the biopsy as illustrated in FIGS. 44A through 44C.

Although embodiments of the present inventive concept are illustrated as using linear servos to stain the biopsy, embodiments of the present inventive concept are not limited to this configuration. For example, the biopsy may be stained using small pumps or microfluidic techniques without departing from the scope of the present inventive concept.

FIG. 45A is a diagram illustrating the biopsy insert with stain being dropped into the biopsy well while the spring seal is pressed down, sealing the area around the biopsy and allowing stain to accumulate in accordance with some embodiments of the present inventive concept. FIG. 45B is a diagram illustrating the biopsy insert while the biopsy is being stained in accordance with some embodiments of the present inventive concept. FIG. 45C is a diagram illustrating the biopsy insert after the staining time has elapsed and the spring seal is released in accordance with some embodiments of the present inventive concept. FIG. 45D is a diagram illustrating the biopsy insert after the stain is removed from the imaging window in accordance with some embodiments of the present inventive concept.

As illustrated, because the spring seal 5210 has sealed the area around the biopsy, the stain pools up and ensures all parts of the biopsy are stained. The spring seal is maintained during this time. When the biopsy has been stained for the appropriate amount of time, the cartridge clamp 4083 is released. The spring tabs on the bottom of the spring seal lift the spring seal off of the imaging window, allowing stain to drain out under the spring seal gasket and away from the biopsy. This allows the spring tabs 5220 on the bottom of the spring seal 5210 to push the spring seal 5210 up off the imaging window 3501 as illustrated in FIGS. 45A through 45D. After the stain is removed from the imaging window. Wash is then pushed onto the biopsy via the same pathway as the stains.

FIGS. 46A and 46B are diagrams illustrating the biopsy insert in accordance with some embodiments. FIG. 46B is a cross section of the biopsy insert of FIG. 46A along the line A-A′ in accordance with some embodiments of the present inventive concept. As illustrated, within the biopsy insert 3596, surrounding the spring seal 5210, is a region filled with an absorbent material 5520. When then spring seal 5210 is released lifting the spring seal gasket 5510, the stain contacts the absorbent material 5520 and it is wicked away from the imaging window 3501, leaving behind a stained biopsy as illustrated in FIG. 46. One of the carriage linear servos 6210 in the carriage 3941 then actuates, washing the biopsy. Substantially all the wash is wicked away by the absorbent material 5520 and the biopsy is ready to be imaged.

In some embodiments, an absorbent material may not be used to remove stain from the imaging window. In these embodiments, pumps or microfluidic techniques may be used to remove the stain without departing from the scope of the present inventive concept.

Once the stain is removed using any method, the biopsy is imaged though the imaging window 3501.

FIG. 47B is a diagram illustrating the stage adapter assembly with the carriage fully extended and the biopsy insert removed from the staining cartridge in accordance with some embodiments of the present inventive concept.

As illustrated, after the biopsy is imaged, the carriage 3941 extends until it contacts the limit switch 4710. Using the Finger Grips 5110 on the sides of the biopsy insert 3596 the user removes the used biopsy insert 3596, the biopsy is set aside for downstream processing, and a fresh biopsy insert 3596 with a different biopsy is placed in the staining cartridge 3594 as illustrated in FIGS. 47A and 47B. The whole process may be repeated for each new biopsy. In some embodiments, the staining cartridge 3594 holds enough stain and wash to stain at least five biopsies, however, embodiments of the present inventive concept are not limited thereto.

In some embodiments, the staining cartridge 3594 may be modified to accommodate more or less volume of stain, allowing for more or fewer biopsies to be stained with one staining cartridge. Embodiments herein are provided as examples only.

It will be understood that embodiments of the disposable, stage adapter and related systems and methods discussed herein are provide as examples only and, therefore, embodiments of the present inventive concept are not limited thereto.

Referring now to FIGS. 79 through 82, operations according to various embodiments of the present inventive concept will be discussed. Histopathology and cytopathology, or the study of microscopic tissue and cellular structure and function, is the basis of disease diagnosis. Histopathology involves the study of microscopically thin sections of tissue attached to glass slides, which are further stained with chromophores to differentially highlight cells and other biological components of interest. Likewise, cytopathology involves the study of cells smeared onto glass slides, which are also stained with chromophores for analysis by a cytopathologist. The process of obtaining the prepared tissue slide for histopathology is a multistep process. The starting point is typically a biopsy or fragment of solid tissue, which is preserved and hardened by either chemical fixation or freezing, is cut into microscopically thin sections using a microtome, after which the tissue sections are placed onto glass slides, further chemically treated to dehydrate, clear, and stain them, and then coverslipped to preserve the integrity of the slide. For cytopathology, the starting point is a slurry of cells obtained by fine needle aspiration or debridement of cells using scraping or brushing. In this case the cells are smeared between glass slides, and the resulting slide is then prepared in a similar fashion as the histopathology slides. Because of the complexities in preparing tissues for histopathology and cytology analysis, typically dedicated technicians are employed to perform this process. Furthermore, because of the need to harden and physically section tissues, the process is slow and difficult to automate. The result of the process is a glass slide with tissue or cells which must be viewed under a microscope, or additionally scanned into a digital image with a whole slide scanner, which presents another lengthy step in an already lengthy and laborious multi-step process. The final step is classification of the sample by a pathologist who views the slide under a microscope or the digital image on a computer screen.

Recently, the advent of digital whole slide scanning has enabled histopathology and cytopathology slides to be digitized for computer-aided analysis or diagnosis. Systems for computer-aided analysis or diagnosis leverage information present in the images to serve as an assist to the human rater by demarcating areas of interest in the image; automatically detecting certain features; measuring quantities such as the size, shape, and arrangement of cells, organelles such as nuclei, or other features; or to perform fully automated diagnosis and/or grading of the tissue pathology. However, the collection of such digital data from histopathology and cytopathology slides collected using traditional methods involves an additional step to digitally scan the image, beyond the already laborious and lengthy multi-step process.

Accordingly, embodiments discussed herein provides an automated digital pathology laboratory which takes as input an intact biological tissue or cell sample, returns an output digital pathology image for pathologist diagnosis with no further user intervention. The invention furthermore optionally performs tasks related to computer-assisted pathology analysis, up to and including rendering a sample classification in an automated manner based on the digital image. The invention enables “sample-to-image” or “sample-to-result” in the field of histopathology and cytopathology, by automating the sample processing steps and removing the need for physical sectioning using optical sectioning microscopy, which inherently results in a useful digital image. Furthermore, as methods in accordance with embodiments discussed herein do not destroy the samples obtained, standard histological or cytological processing may also be performed on the sample.

Referring now to FIG. 79, operations performed by systems and device in accordance with embodiments of the present inventive concept will be discussed. Systems and methods in accordance with embodiments discussed herein begin at block 7900 by receiving a biological sample an input. Details with respect to “biological samples” are discussed further below. The received biological sample is processed by the system (block 7910). Processing the received biological sample includes imaging the sample and returning an intermediate imaging output or result (block 7920). The imaging output/result may serve as an image for direct human evaluation. However, operations may proceed to block 7930 where the intermediate imaging output/result may be further processed (second process) by an image processing and sample classification system (block 7930). The second process provides a final sample classification result (block 7940). Further details with respect to these processes will be discussed further below with respect to the flowcharts of FIGS. 80 through 82.

Referring now to FIG. 80, operations begin at block 8000 by receiving a biological sample. In some embodiments, the biological sample may be an unprocessed sample as shown in block 8100 of FIG. 81 and block 8300 of FIG. 83. An unprocessed sample may be an unprocessed tissue biopsy, fragment, slice, smear, or scrape. As used herein, “unprocessed” refers to a fresh, unfixed, unstained, non-preserved, and intact tissue biopsy, fragment, slice, smear or scrape. However, embodiments of the present inventive concept are not limited to this configuration. For example, in some embodiments, the sample may be a fixed or preserved tissue biopsy, fragment, slice, smear, or scrape without departing from the scope of the present inventive concept. In some embodiments, the sample may be a frozen and thawed tissue biopsy, fragment, slice, smear, or scrape. The sample may also be a microscopically thin tissue section or smear prepared on a glass or plastic slide; or a block of tissue embedded in paraffin wax.

Furthermore, in some embodiments, the biological sample may be a “processed” sample, i.e. a previously stained biological sample, either fresh, fixed, wax-embedded, or previously frozen as shown in block 8210 of FIG. 82.

The biological sample is introduced into a sample processing and imaging System (blocks 8010 and 8010′). These block 8010 and 8010′ may include multiple processes therein. As shown in FIGS. 81 and 83, the multiple processes of blocks 8010 and 8010′ both include three subprocesses blocks 8120/8320, 8130/8330 and 8140/8340. At blocks 8120/8320, a sample processing system may process the sample for microscopic imaging by applying fluorescent stains and wash solutions and removing excess stain from the sample. This sample processing method may be used when the biological sample is an unstained sample (unprocessed—blocks 8100 and 8300). If the sample has been previously stained (processed—block 8210 of FIG. 82), operations of block 8120/8320 may be eliminated from the process as shown in FIG. 82. In FIG. 82, operations proceed directly to the sample positioner and imager (block 8230) without block 8120/8320.

Operations of block 8120/8320 may further include a staining cartridge as discussed above in accordance with some embodiments of the present inventive concept. As discussed, the staining cartridge automatically applies stain and wash solutions to the sample and removes solutions from the sample to prepare it for imaging. As discussed above, staining cartridge is inserted into the sample positioner and imager (block 8130/8230/8330) via, for example, the carriage discussed above. The sample positioner and imager may further include a stage adaptor assembly that serves to attach the sample cartridge containing the biological sample, to a mechanical XY translation stage that steps the sample in increments systematically over an optical sectioning microscope, in order to obtain microscopic images covering the surface area of the sample.

In some embodiments, the optical sectioning microscope includes a structured illumination microscope operating in fluorescence mode, for example, the microscope discussed in U.S. Pat. No. 10,042,150, the disclosure of which is hereby incorporated herein by reference as if set forth in its entirety. The structured illumination microscope may also be operated in reflectance mode optionally in addition to fluorescence mode. In some embodiments, the optical sectioning microscope may include, for example, a confocal microscope, multiphoton microscope, deconvolution microscope, light sheet or planar illumination microscope. The optical sectioning microscope uses a plurality of illumination wavelengths and optical filters to obtain a plurality of microscopic images of the sample corresponding to the plurality of contrasting agents or stains applied to the sample, or according to the reflectance of the sample. The microscopic imaging system obtains a plurality of images of the biological sample at a plurality of locations over the area of the sample, by moving the sample systematically (including but not limited to a serpentine, or raster pattern) with relation to the microscope objective lens, or alternatively by moving the microscopic imaging system systematically with relation to the biological sample. An autofocus routine is used at each location to focus the microscope onto the surface of the sample, which acts by optimizing a focus function as the objective lens is advanced in the direction perpendicular to the tissue surface using a mechanical Z Translation Stage. The resulting grayscale images are then input into subsystem image processor to process images obtained from the microscopic imaging system into an intermediate image result of the biological sample (block 8140/8240/8340). In some embodiments, individual images obtained from each location of the sample may be stitched together to obtain a mosaic or panorama image of the biological sample for each of the plurality of illumination wavelengths or imaging channels, to provide the intermediate processed image (block 8020).

Further, the plurality of mosaic or panorama images, corresponding to the multiple contrast agents or stains applied to the sample, may also be combined into a single image in which each imaging channel is remapped into a new colormap. In some embodiments, the colormap is obtained by color deconvolution of hematoxylin and eosin stained slide images of a similar biological sample, in order to render the image of the biological sample to replicate that of a hematoxylin and eosin slide. Slides stained with dyes other than hematoxylin and eosin, for instance Diff Quik, Papanicolau stain, trichrome stains, periodic acid schiff stain, Jones silver stain, Oil red O, or peroxidase-stained immunohistochemistry slides, may also be used for color deconvolution to obtain colormaps for rendering a plurality of grayscale images into single color images.

In some embodiments, other colormaps may be applied to combine multiple grayscale images of the sample representing multiple contrasting agents or sources, into a single image. In some embodiments a merged image, in combination with a plurality of single-channel images corresponding to a plurality of acquisition wavelengths, will serve as the input into a subsystem. In some embodiments, the combined single image will serve as the input to subsystems. For example, image evaluation may be performed by human interpretation, automated interpretation, and/or computer aided detection without departing from the scope of the present inventive concept.

Operations of block 8165/8265 include a method for transmitting generated images to a remote viewing system for navigation and annotation; transmission of the original image from the source computer system over a network to a remotely hosted server; conversion of the transmitted image into a multiresolution pyramid of images; storage of the multiresolution pyramid of images, with associated image metadata, in a database; accessing of a stored multiresolution image pyramid, using a unique identifier, from the database, and display of the associated image pyramid in a web viewer.

The image viewer (block 8175/8275) also includes a user interface that enables annotation, by drawing of a polygonal region, and text documentation linked to the polygonal region, for a linked multiresolution image pyramid.
